No inflow from one of two sources
First of all, you should bake the sim with a higher resolution. The resolution is not just about quality, it determines how the fluid acts. Using a resolution as low as 44 just doesn't make sense.

That being said, one possible reason why the inflow does not work is that it may be too close to the edge of the domain. Inflow objects need some space around them.

While the general wisdom is that the domain should be as small as possible, this can cause problems. Increasing the domain size should always be part of the trouble-shooting process when a fluid simulation won't work properly.
